Feliway Classic Refill provides a replacement 48ml pheromone vial for the Feliway Classic diffuser. One refill delivers approximately 30 days of continuous calming support for stressed or anxious cats.

The vial contains a synthetic copy of the feline facial pheromone that cats naturally produce when they feel safe and comfortable. When diffused continuously, it helps reduce stress signs including spraying, scratching, hiding, and overgrooming. Simply swap the empty vial for the refill in your existing Feliway Classic diffuser.

Feliway Classic is the original and most widely used feline pheromone product globally. Regular monthly refill replacement ensures your cat receives consistent calming support without interruption.
